XDUOO MT-602 Tube Headphone Amplifier

The XDUOO MT-602 is a hybrid headphone amplifier that pairs a dual 6J1 tube preamp stage with a Class-A transistor output buffer. It is built for listeners who want the warm, sweet tonality of tubes combined with the strong driving force and speed of solid-state circuitry.

Hybrid Circuit Installation and Tube Care

The unit connects to a source via line-level inputs and feeds headphones through its front-panel output; a rear line-out also allows use as a tube preamplifier for powered speakers or integrated amps. Installation is straightforward, though the glass 6J1 tubes require careful seating and will eventually need replacement as they age.

1300 mW Output Power and Headroom

The Class-A transistor buffer delivers up to 1300 mW, providing ample headroom for most high-impedance and planar-magnetic headphones. Very low-sensitivity models or demanding balanced loads may still exceed the available current, while users seeking higher voltage swing for electrostatic systems will need a dedicated energiser.

Questions about this item

How can I verify the MT-602 is operating correctly after connecting my headphones?

Power the unit on; the built-in mute relay will silence the output briefly while the double 6J1 tubes warm up, then music should play without any turn-on pop.

What accessories are included with the MT-602 and what must I provide separately?

The amplifier itself is supplied; you will need to add a source component, interconnect cables, and headphones or active speakers to complete the system.

Which version of the MT-602 should I choose for maximum headphone driving power?

The single model listed delivers up to 1300 mW in Class-A, so there is no alternative capacity to select.
